Because the more things a tester knows, the more value he adds to the project.

If the tester can not only test but also provide customer support, participate in code reviews, write test automation scripts, create unit tests, is he more valuable than another tester than just does functional testing?

Much more valuable.

Being a versatile tester is not only more valuable for the company but also for your career.

You can target not only manual testing jobs but also test automation, performance testing, api testing, hybrid testing roles too.

If you focus on one testing type only, your future testing career may be in danger.

But, how can you find the time to learn all these new skills?

And who will provide the training?

And what should you learn?

5. YOU ARE NOT TAKING RESPONSIBILITY FOR YOUR TRAINING

No one will provide you the training for growing your career except yourself.

You may know this joke:

the person that can solve all your problems is the one that looks at you when you are in front of the mirror.

Few companies offer training programs to testers these days.

And if they do, the courses are for skills that the company needs which may be different from what the tester needs.

So, to keep your career afloat, you need to take responsibility for

what you learn

how you learn

how to find the time for learning

6. YOU ARE KEEPING THE SAME TESTING JOB FOR A LONG TIME

This is the last warning that your testing career may be in danger.

There are companies out there where you can work for a long time and have a very rewarding experience.

If you can move between projects or departments or even better if you can change job responsibilities often, there is no need to change your job.

All these changes will keep you improving and learning.

But, if you work on the same product for a few years, do the same testing and within the same team, chances are that you stopped improving yourself a long time ago.

And if there is one thing that shows that your career may not have a future, this is the one:you are not learning new things every day.
